USPP37037P2 - Strawberry plant named ‘HOB-R490’ - Google Patents

Abstract

A new variety of strawberry plant named ‘HOB-R490’ that has high hardness of fruit body, with the fruit having a medium size and a light red core.

Description

Common name: Strawberry.

Botanical classification: Fragaria x ananassa Duchesne ex Rozier.

Variety denomination: ‘HOB-R490’.

CROSS-REFERENCE TO PRIOR APPLICATION

This application follows Japanese plant variety rights application No. 37438 filed May 24, 2024, the entire content of which is incorporated by reference herein.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of strawberry, Fragaria x ananassa Duchesne ex Rozier, which has been given the variety denomination ‘HOB-R490’.

The variety is distinguished by its high hardness of fruit body, with the fruit having achenes positioned deep below the surface and a light red core, that distinguish it notably from its female parent ‘Pechika Pure’ (fruit having achenes positioned shallow below the surface and a yellowish pink (RHS 33C) core).

ORIGIN OF THE VARIETY

The parent varieties are ‘R392-43’ (male parent) (not patented in the U.S.) and ‘Pechika pure’ (female parent) (not patented in the U.S.).

The variety was asexually reproduced by runners in Higashikagura-cho, Kamikawa-gun, Hokkaido, Japan.

In March 2021, the male variety ‘R392-43’ and female variety ‘Pechika pure’ were crossed in a greenhouse in Higashikagura-cho, Kamikawa-gun, Hokkaido, Japan.

In 2021, the resulting seedlings were sown and raised.

In 2022, the raised seedlings were planted and grown in a test field located in Higashikagura-cho, Kamikawa-gun, Hokkaido, Japan, and two individuals with superior characteristics were selected.

In 2023, the test was carried out again, and ‘HOB-R490’ was selected for its high hardness of fruit body and its taste.

On May 24, 2024, an application for plant variety rights No. 37438 was filed for the present variety in the Japanese Plant Variety Protection Office of the Ministry of Agriculture, Forestry and Fisheries (MAFF), Japan.

Cultivation of the variety does not require special conditions or treatments.

Proper planting time is from the end of March to the beginning of April.

Flowering time is from the middle of May.

Harvesting time is from the end of June to the end of November.

The variety is currently mainly intended for fruit production.

SUMMARY OF THE VARIETY

The variety is distinguished by its high hardness of fruit body and rich taste with strong sweetness and acidity, with the fruit having a light red (RHS 40C) core, that distinguish it notably from its female parent ‘Pechika Pure’ (fruit having a yellowish pink (RHS 33C) core). The variety is also distinguished by its upright plant growth habit and cylindrical fruit shape, which distinguish it notably from its male parent ‘R392-43’ (semi-upright plant growth habit and conical fruit shape).

A comparison table with the male parent ‘R392-43’ is as follows (evaluation based on averages).
